Pulled muscle in hy hip. Should I take it easy and rest or keep doing stretches?

I seem to have pulled a muscle in my hip during physical therapy. My PT started me doing some new stretces for my hip and I don't know what happened but now I keep getting this sharp pain in my right hip groin area when I try to walk or lift my knee up. Should I keep doing some stretching or just ice it and rest? I don't see him again until Tuesday.
